Acceleration Flashcards
1
Q
Acceleration
A
Acceleration is the rate of change of velocity with respect to time
2
Q
Unit of acceleration
A
The unit of acceleration is the metre per second squared (m/s*2)
3
Q
Velocity-time graph
A
A velocity-time graph of a body moving with a constant acceleration is a straight line
The slope is the acceleration
The area under the graph is the distance travelled
4
Q
Acceleration due to gravity
A
In the absence of air resistance, all objects near the Earth’s surface, if released, will fall downwards with the same acceleration. This acceleration is called acceleration due to gravity. Its symbol is ‘g’
